For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of their instruction manual, and will not be described in detail here.

[0045] In summary, the working principle of the test-free mold and mold-closing method used in the process of making wind turbine blades is that the opening and closing top mold base 2 is opened relative to the fixed bottom mold base 1 by the operation of the mold opening and closing drive assembly, and then the wind turbine blades can be made. After the SS skin is equipped in the mold cavity of the SS surface, the automatic telescopic frame is adjusted to adjust the position of multiple laser rangefinders 7 relative to the fixed bottom mold base 1, so that multiple laser rangefinders 7 are in place relative to the measuring point, and then the height of the SS skin from the laser rangefinder 7 is measured, and multi-point detection is formed according to the specific size of the wind turbine blade, and a record is formed by the computer 6. After the web in the mold cavity of the PS surface is bonded to the PS skin, the movable bracket 3 is moved and adjusted relative to the fixed bottom mold base 1, and the automatic telescopic frame on the movable bracket 3 is controlled to enter the top of the mold cavity of the PS surface, and multiple laser rangefinders 7 are used to measure the height of the web flange to the laser rangefinder 7, and multi-point detection is formed according to the specific size of the wind turbine blade. Detection is performed and a record is formed through the computer 6. After the data collection is completed, the computer 6 summarizes the measured data to simulate the mold closing conditions of the PS surface and the SS surface. Similarly, the glue layer of other bonding areas is measured to achieve the purpose of free mold closing measurement. The subsequent production of wind turbine blades can be carried out according to the measured data. The telescopic adjustment work of the automatic telescopic frame is realized by changing the position of the telescopic rod of the electric control rod 17 relative to the electric control rod 17. The opening and closing mold drive assembly works through the two electric cooperative rods 25 to realize the traction drive of the winding rope 24. The movement of the winding rope 24 realizes the rotation drive of the drive disk 23. The rotation of the drive disk 23 realizes the rotation drive of the drive shaft 21. The rotation of the drive shaft 21 realizes the rotation drive and control of the support seat 28 relative to the support seat 22, thereby achieving the rotation and control of the opening and closing top mold seat 2 relative to the fixed bottom mold seat 1, and then facilitating the control of the rotation opening and rotation closing of the opening and closing top mold seat 2 relative to the fixed bottom mold seat 1.

[0046] Below we take six-point detection as an example to form the specific detection data marking and calculation steps as follows:

[0047] As attached Fig.14 As shown, the relative position of the laser rangefinder 7 is adjusted to measure the skin where the web is bonded to the PS surface, and A, B, C, D, E, and F are used as marks for the six measuring points;

[0048] As attached Fig.15 As shown, adjust the relative position of the laser rangefinder 7, measure the skin of the SS surface, and use H, I, J, K, L, and M as marks of the six measuring points;

[0049] As attached Fig.16 As shown, the PS surface and SS surface mold closing conditions are simulated, and it can be known that (A+M) height / (B+L) height / (C+K) height / (D+J) height / (E+I) height / (F+H) height - (laser rangefinder 7 height X2) = thickness of the adhesive layer under the web.

[0050] The application of the trial mold-free mold and the mold-closing method in the process of manufacturing wind turbine blades avoids the error of personnel in measuring plasticine in terms of quality of the wind turbine blades, eliminates the use of plasticine in the trial mold-closing step in terms of cost, reduces the cost of plasticine production, and saves the trial mold-closing step in terms of efficiency, which can save more than 2 hours of time.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

A plurality of laser rangefinders (7) are used to measure the height of the web flange to the laser rangefinders (7), and a multi-point detection is performed according to the specific size of the wind turbine blade, and a record is formed by a computer (6); S3. After data collection is completed, the computer (6) summarizes the measured data to simulate the mold closing conditions of the PS surface and the SS surface. Similarly, the adhesive layers of other bonding areas are measured to achieve the purpose of free mold closing measurement. The subsequent production of wind turbine blades can be carried out according to the measured data.
